Electrochromism and Swelling of Polypyrrole Membranes: An Electrochemical and Ellipsometric Study
Figure 7
Calculated thickness, d, and optical indices, n, k, for the Ppy layers already described in Figure 3(a), Ea = 1.2 V, = 20 s. SDS solution, = 546 nm. The different values n and k correspond to the resulting fitted values for different set of thicknesses.
